Steca PR 03-05
PR 0303, PR 0505
Description
The Steca PR 0303 and Steca PR 0505 solar charge controllers are ideal for use in small solar home systems.
This means that lamps, radios or a small television can be operated without any issue. All consumers can be switched off using the manual load switch on the controller. Due to its extremely low self-consumption, the Steca PR is particularly suitable for professional applications in telecommunications and traffic engineering. As it is a serial controller, it is highly flexible with regard to the type of power source connected. Thanks to its electronic fuse, the charge controller is absolutely maintenance-free and robust.
